Draining the Water Heater
!
CAUTION: Shut off gas to the
water heater at the gas control
(thermostat) gas cock or manual
shut-off valve before draining
water.
!
DANGER: Before manually
operating the temperature and
pressure relief valve, make certain
no one will be exposed to the hot
water released by the valve. The
water drained from the tank may be
hot enough to present a scald
hazard and should be directed to a
suitable drain to prevent injury or
damage.
In order to drain the water heater, turn
off the cold water supply. Open a hot
water faucet or lift the handle on the
relief valve to admit air to the tank.
Attach a garden hose to the drain
valve on the water heater and direct
the stream of water to a drain. Open
the valve.
Housekeeping
Visually inspect pilot burner and
relight if necessary.
To ensure sufficient ventilation
and combustion air supply, proper
clearances must be maintained.
When installed in a closet, DO
NOT block or obstruct any of
the combustion air inlet openings
located around the perimeter of
the water heater. A minimum
of 1” is required between these
combustion air inlet openings and
any obstruction.
Routine Preventative Maintenance
Properly maintained, your water heater
will provide years of dependable
trouble-free service.
It is recommended that a periodic
inspection of the gas control
(thermostat), burner, relief valve,
internal flue-way and venting system
should be made by service personnel
qualified in gas appliance repair.
It is suggested that a routine
preventative maintenance program be
established and followed by the user.
At least once a year, lift and release
the lever handle on the temperature
pressure relief valve, located near
the top of the water heater, to make
certain the valve operates freely. Allow
several gallons to flush through the
discharge line to an open drain.
NOTICE: If the temperature and
pressure relief valve on the hot
water heater discharges periodically,
this may be due to thermal
expansion in a closed water system.
Contact the water supplier or your
plumbing contractor on how to
correct this. DO NOT plug the relief
valve outlet.
A water heater’s tank can act as a
settling basin for solids suspended
in the water. It is therefore not
uncommon for hard water deposits to
accumulate in the bottom of the tank.
If allowed to accumulate, these solids
can cover the gas control (thermostat)
sensors, causing the sensors to operate
erratically. Because accumulated
solids can prevent the gas control
(thermostat) sensors from accurately
reading the water temperature, the
water at the fixture can be hotter
than the gas control (thermostat) dial
setting. It is suggested that a few
quarts of water be drained from the
water heater’s tank every month to
clean the tank of these deposits.
Rapid closing of faucets or solenoid
valves in automatic water using
appliances can cause a banging noise
heard in a water pipe. Strategically
located risers in the water pipe system
or water hammer arresting devices can
be used to minimize the problem.
The anode rod should be removed
from the water heater’s tank annually
for inspection and replaced when more
than 6” of core wire is exposed at
either end of the rod.
Make sure the cold water supply is
turned off before removing anode rod.
This water heater incorporates a
combustion shut off device that shuts
the operation of the water heater down
if undesirable combustion conditions
occur. Such as the presence of
flammable vapors or blockage of the
combustion air inlet openings. Please
contact a Qualified Service Technician
if this occurs.
!
DANGER: Before
manually operating the
relief valve, make certain
no one will be exposed to
the danger of the hot water
released by the valve. The
water may be hot enough to
create a scald hazard. The
water should be released
into a suitable drain to
prevent injury or property
damage.
DANGER: Failure to
perform the recommended
Routine Preventative
Maintenance can harm the
proper operation of this
water heater, which can
cause carbon monoxide
dangers, excessive hot
water temperatures and
other potentially hazardous
conditions.
!
DANGER: Combustible
materials, such as
clothing, cleaning
materials, or flammable
liquids, etc., must not be
placed against or next to
the water heater.
!
!
DANGER: Hotter water
increases the potential for
Hot Water Scalds.
